    摘要： Techniques are disclosed relating to reclaiming data on recording media. In one embodiment, an apparatus has a solid-state memory array including a plurality of blocks. The solid-state memory array may implement a cache for one or more storage devices. Respective operational effects are determined relating to reclaiming ones of the plurality of blocks. One of the plurality of blocks is selected as a candidate for reclamation based on the determined operational effects, and the selected block is reclaimed. In some embodiments, the determined operational effects for a given block indicate a number of write operations to be performed to reclaim the given block. In some embodiments, operational effects are determined based on criteria relating to assigned quality-of-service levels. In some embodiments, operational effects are determined based on information relating to virtual storage units.

    摘要： A cache and/or storage module may be configured to reduce write amplification in a cache storage. Cache layer write amplification (CLWA) may occur due to an over-permissive admission policy. The cache module may be configured to reduce CLWA by configuring admission policies to avoid unnecessary writes. Admission policies may be predicated on access and/or sequentiality metrics. Flash layer write amplification (FLWA) may arise due to the write-once properties of the storage medium. FLWA may be reduced by delegating cache eviction functionality to the underlying storage layer. The cache and storage layers may be configured to communicate coordination information, which may be leveraged to improve the performance of cache and/or storage operations.

    摘要： A storage module may be configured to perform log storage operations on a storage log maintained on a non-volatile storage medium. An I/O client may utilize storage services of the storage module to maintain an upper-level log. The storage module may be configured to coordinate log storage and/or management operations between the storage log and the upper-level log. The coordination may include adapting a segment size of the logs to reduce write amplification. The coordination may further include coordinating validity information between log layers, adapting log grooming operations to reduce storage recovery overhead, defragmenting upper-level log data within the storage address space, preventing fragmentation of upper-level log data, and so on. The storage module may coordinate log operations by use of log coordination messages communicated between log layers.

    摘要： A storage module is configured to determine a health metric of a storage division of a solid-state storage medium. The health metric may comprise a combination of factors, including, but not limited to: wear level, performance (e.g., program time, erase time, and the like), error rate, and the like. A wear level module may configure storage operations to reduce the wear rate of storage divisions having poor health metrics and/or heath metrics that are degrading more quickly than other storage divisions. Reducing wear rate may include deferring grooming operations, delaying use for storage operations, temporarily retiring the storage division, or the like. Storage divisions may be brought back into service at normal use rates in response determining that other portions of the storage media have been worn to the point that they exhibit similar health and/or reliability characteristics.
